Did you know that when you finish your fsck check (run at startup after holding down command-S to get into single user mode), instead of typing "reboot" to go back to the System, you can type "bye bye" to accomplish the same thing?
Some UNIX-Apple humor... :)
[Editor's note: I didn't actually test this one myself, but it's late on a Sunday night and I thought it was pretty humorous ... if anyone would like to verify it, let us know if it worked!]
